• Contacts that are scratched, soiled, or have fingerprints on them may result in faulty connections or corrosion, which may lead to malfunctions. If the contacts get soiled, clean them with a soft cloth.

Focusing/control ring

The focusing/control ring can be used as either a focusing ring or a control ring.

Use as a Focusing Ring
Set the Focusing/control selector switch to FOCUS. Set the focus mode (AF/MF) using the camera’s menu.

• When using a tripod, it is recommended that you set the image stabilizer switch to OFF.

• Even with a monopod, the Image Stabilizer will be as effective as during hand-held shooting. However, depending on the shooting conditions, there are cases in which the Image Stabilizer effect may be less effective.

•  When shooting a still subject, it compensates for camera shake in all directions.

• It compensates for vertical camera shake during panning shots in a horizontal direction and compensates for horizontal camera shake during panning shots in a vertical direction.
